4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Loratadine 10mg Tablets are indicated for the symptomatic treatment of allergic rhinitis and chronic idiopathic urticaria.
4.2 Posology and method of administration
Adults, including the elderly, and children 12 years of age and over: One 10mg tablet once daily.
Children 2 to 12 years of age with:
Body weight more than 30 kg: 10mg once daily (one tablet). Body weight 30 kg or less: 5ml (5mg) of the syrup once daily. The 10mg strength tablet is not appropriate in children with a body weight less than 30 kg.
Efficacy and safety of Loratadine 10mg Tablets in children under 2 years of age has not been established in this age group.
Patients with severe liver impairment should be administered a lower initial dose because they may have reduced clearance of loratadine. An initial dose of 10mg every other day is recommended for adults and children weighing more than 30 kg
No dosage adjustments are required in the elderly or in patients with renal insufficiency.
4.3 Contraindications
Loratadine 10 mg Tablets are contraindicated in patients who are hypersensitive to the active substance or to any of the excipients listed in section 6.1.
4.4 Special warnings and precautions for use
Loratadine 10 mg Tablets should be administered with caution in patients with severe liver impairment (see section 4.2).
This medicinal product contains lactose; thus patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucosegalactose malabsorption should not take this medicine.
The administration of Loratadine 10mg Tablets should be discontinued at least 48 hours before skin tests since antihistamines may prevent or reduce otherwise positive reactions to dermal reactivity index.
4.5 Interaction with other medicinal products and other forms of interaction
When administered concomitantly with alcohol, Loratadine 10mg tablet have no potentiating effects as measured by psychomotor performance studies.
Potential interaction may occur with all known inhibitors of CYP3A4 or CYP2D6 resulting in elevated levels of loratadine (see Section 5.2), which may cause an increase in adverse events.
Increase in plasma concentrations of loratadine has been reported after concomitant use with ketoconazole, erythromycin and cimetidine in controlled trials, but without clinically significant changes (including electrocardiographic).
Paediatric population
Interaction studies have only been performed in adults.
4.6 Fertility, pregnancy and lactation
A large amount of data on pregnant women (more than 1000 exposed outcomes) indicate no malformative nor feto/neonatal toxicity of loratadine. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity (see section 5.3).
As a precautionary measure, it is preferable to avoid the use of Loratadine Tablets during pregnancy.
Loratadine is excreted in breast milk. Therefore, the use of Loratadine is not recommended in breast-feeding women.
There are no data available on male and female fertility.
4.7 Effects on ability to drive and use machines
In clinical trials that assessed driving ability, no impairment was observed in patients receiving loratadine. Loratadine tablets has no or negligible influence on the ability to drive and use machines. However, patients should be informed that very rarely some people experience drowsiness, which may affect their ability to drive or use machines.
4.8 Undesirable effects
Summary of the safety profile
In clinical trials involving adults and adolescents in a range of indications including allergic rhinitis (AR) and chronic idiopathic urticarial (CIU), at the recommended dose of 10mg daily, adverse reactions with Loratadine were reported in 2% of patients in excess of those treated with placebo. The most frequent adverse reactions reported in excess of placebo were somnolence (1.2%), headache (0.6%), increased appetite (0.5%) and insomnia (0.1%).

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme, website www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
4.9 Overdose
4.9 OverdoseOverdosage with loratadine increased the occurrence of antocholinergic symptoms. Somnolence, tachycardia and headache have been reported with overdoses.
In the event of overdose, general symptomatic and supportive measures are to be instituted and maintained for as long as necessary. Administration of activated charcoal as a slurry with water may be attempted. Gastric lavage may be considered. Loratadine is not removed by haemodialysis and it is not known if loratadine is removed by peritoneal dialysis. Medical monitoring of the patient is to be continued after emergency treatment.
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: antihistamines – H1 antagonist, ATC code R06A X13
Loratadine the active ingredient in Loratadine 10mg Tablets, is a tricyclic antihistamine with selective, peripheral H1 receptor activity.
Loratadine has no clinically significant sedative or anticholinergic properties in the majority of the population and when used at the recommended dosage.
During long-term treatment there were no clinically significant changes in vital signs, laboratory test values, physical examinations of electrocardiograms. Loratadine has no significant H2-receptor activity. It does not inhibit norepinephrine uptake and has practically no influence on cardiovascular function or on intrinsic cardiac pacemaker activity.
Human histamine skin wheal studies following a single 10 mg dose has shown that the antihistamine effects are seen within 1–3 hours reaching a peak at 8–12 hours and lasting in excess of 24 hours. There was no evidence of tolerance to this effect after 28 days of dosing with loratadine.
Over 10,000 subjects (12 years and older) have been treated with loratadine 10mg tablets in controlled clinical trials. Loratadine 10mg tablets once daily was superior to placebo and similar to clemastine in improving the effects on nasal and non-nasal symptoms of AR. In these studies somnolence occurred less frequently with loratadine than with clemastine and about the same frequency as terfenadine and placebo.
Among these subjects (12 years and older), 1000 subjects with CIU were enrolled in placebo controlled studies. A once daily 10 mg dose of loratadine was superior to placebo in the management of CIU as demonstrated by the reduction of associated itching, erythema and hives. In these studies the incidence of somnolence with loratadine was similar to placebo.
Approximately 200 paediatric subjects (6 to 12 years of age) with seasonal allergic rhinitis received doses of loratadine syrup up to 10 mg once daily in controlled clinical trials. In another study, 60 paediatric subjects (2 to 5 years of age) received 5 mg of loratadine syrup once daily. No unexpected adverse events were observed.
The paediatric efficacy was similar to the efficacy observed in adults.
5.2 Pharmacokinetic properties
Loratadine is rapidly and well-absorbed. Concomitant ingestion of food can delay slightly the absorption of loratadine but without influencing the clinical effect. The bioavailability parameters of loratadine and of the active metabolite are dose proportional.
Loratadine is highly bound (97% to 99%) and its active major metabolite desloratadine (DL) moderately bound (73% to 76%) to plasma proteins.
In healthy subjects, plasma distribution half-lives of loratadine and its active metabolite are approximately 1 and 2 hours respectively.
Biotransformation
After oral administration, loratadine is rapidly and well absorbed and undergoes an extensive first pass metabolism, mainly by CYP3A4 and CYP2D6. The major metabolite-desloratadine (DL)- is pharmacologically active and responsible for a large part of the clinical effect. Loratadine and DL achieve maximum plasma concentrations (Tmax) between 1–1.5 hours and 1.5–3.7 hours after administration, respectively.
Approximately 40% of the dose is excreted in the urine and 42% in the faeces over a 10 day period and mainly in the form of conjugated metabolites. Approximately 27% of the dose is eliminated in the urine during the first 24 hours. Less than 1% of the active substance is excreted unchanged in the active form, as loratadine or DL.
The mean elimination half-lives in healthy adult subjects were 8.4 hours (range = 3 to 20 hours) for loratadine and 28 hours (range = 8.8 to 92 hours) for the major active metabolite.
Renal impairment
In patients with chronic renal impairment, both the AUC and peak plasma levels (Cmax) increased for loratadine and its active metabolite as compared to the AUCs and peak plasma levels (Cmax) of patients with normal renal function. The mean elimination half-lives of loratadine and its active metabolite were not significantly different from that observed in normal subjects. Haemodialysis does not have an effect on the pharmacokinetics of loratadine or its active metabolite in subjects with chronic renal impairment.
In patients with chronic alcoholic liver disease, the AUC and peak plasma levels (Cmax) of loratadine were double while the pharmacokinetic profile of the active metabolite was not significantly changed from that in patients with normal liver function. The elimination half-lives for loratadine and its metabolite were 24 hours and 37 hours, respectively, and increased with increasing severity of liver disease.
The pharmacokinetic profile of loratadine and its active metabolite is comparable in healthy adult volunteers and in healthy geriatric volunteers.
